Definitions
- Embodiments of the invention relate to the field of microelectronic processing technology, and specifically relate to a mechanical chuck and a plasma processing apparatus.
- PVD physical vapor deposition
- TSV through silicon via
- an electrostatic chuck is commonly used to fix the wafer in the PVD technique.
- the electrostatic chuck cannot electrostatically adsorb the wafer due to large thickness and high stress of the film deposited in the through silicon via; in addition, in a subsequent packaging process, the thickness of the wafer is reduced and a glass substrate is adhered to the bottom of the wafer, so the electrostatic chuck cannot electrostatically adsorb the wafer having the glass substrate.
- a mechanical chuck is required to fix the wafer instead of the electrostatic chuck.
- FIG. 1 is a cross-sectional view of a conventional PVD apparatus.
- the PVD apparatus includes a reaction chamber 10 , and a target material 14 is provided at the top inside the reaction chamber 10 and is electrically connected to a direct current (DC) power supply (not shown in the drawings).
- a mechanical chuck is provided below the target material 14 inside the reaction chamber 10 , and includes a base 11 and a locking ring 13 , wherein the base 11 is used for carrying a wafer 12 and is electrically connected to a radio frequency (RF) power supply 15 , and the locking ring 13 is used for pressing an edge region of the wafer 12 disposed on the base 11 during the process so as to fix the wafer 12 onto the base 11 .
- RF radio frequency
- a negative bias voltage is applied to the target material 14 by the DC power supply to excite a process gas in the reaction chamber 10 to form plasma, and attract energetic particles in the plasma to bombard the target material 14 , so as to allow metal atoms on a surface of the target material 14 to escape and be deposited on the wafer 12 .
- RF power is applied to the base 11 by the RF power supply 15 to form a negative bias voltage on an upper surface of the wafer 12 , which can attract the sputtered metal atoms to be deposited into the through silicon via, thereby filling the through silicon via.
- the degree to which the plasma is controlled by the negative bias voltage is generally measured by resputter rate, which refers to a ratio (usually larger than one) of the average thin-film resistance under RF power to the average thin-film resistance without RF power, and a larger ratio means that the plasma can bombard the surface of the wafer more vertically, thus, a through silicon having a relatively large depth-to-width ratio (larger than 6:1) can be filled.
- the resputter rate of the electrostatic chuck is 1.18 while the resputter rate of the mechanical chuck is only 0.88.
- the capacitor is formed between one or more elements electrically connected to the RF power supply and the ground with plasma accommodated therebetween, and the term “capacitor area” refers to a total area of a surface of the one or more elements exposed in the plasma.
- the capacitor area thereof is an area of the upper surface of the wafer.
- the base 11 , the wafer 12 and the locking ring 13 are required to be electrically connected with each other to allow the three to at a same voltage level, which makes that the RF voltage is applied to each of the base 11 , the wafer 12 and the locking ring 13 , so the capacitor area of the mechanical chuck is the sum of the areas of upper surfaces of the wafer 12 and the locking ring 13 .
- the negative bias voltage formed on the upper surface of the wafer 12 is reduced due to the nearly doubled capacitor area of the mechanical chuck compared to that of the electrostatic chuck, thereby reducing resputter rate.
- the negative bias voltage can be increased by increasing RF power, the increase of RF power will result in not only an increasing cost for use but also a rising temperature of the reaction chamber 10 and the wafer 12 , thereby adversely affecting lifetime of the reaction chamber 10 and process quality.
- Embodiments of the invention are intended to solve at least one of the technical problems existing in the conventional art, and provide a mechanical chuck and a plasma processing apparatus, which can increase a negative bias voltage formed on an upper surface of a workpiece to be processed without increasing RF power, thereby improving resputter rate.
- a mechanical chuck which includes a base for carrying a workpiece to be processed and a fixing assembly, the fixing assembly including a locking ring, an insulation ring and a spacer ring sequentially stacked from bottom to top, wherein the locking ring is used for pressing an edge region of the workpiece disposed on the base during a process so as to fix it onto the base; an orthogonal projection of the spacer ring on an upper surface of the locking ring overlaps with the upper surface of the locking ring; the insulation ring is used to electrically insulate the locking ring from the spacer ring, an inner circumferential wall of the insulation ring, a portion of the upper surface of the locking ring inside the inner circumferential wall and a portion of a lower surface of the spacer ring inside the inner circumferential wall together form a first groove, and an outer circumferential wall of the insulation ring, a portion of the upper surface of the locking ring outside the outer circumferential wall and a portion of the lower
- the first groove has a depth-to-width ratio larger than 7:1
- the second groove has a depth-to-width ratio larger than 7:1.
- the first groove and the second groove each have a width smaller than 3 mm.
- the sum of heights of the insulation ring and the spacer ring in a direction perpendicular to the upper surface of the locking ring is no larger than 8 mm.
- a material of the insulation ring includes ceramic or quartz.
- the insulation ring is formed by plating an insulation material onto the upper surface of the locking ring.
- a material of the spacer ring includes a metal or an insulation material.
- the fixing assembly further includes an insulation screw used for fixing the locking ring, the insulation ring and the spacer ring together.
- a plasma processing apparatus including a reaction chamber, in which a mechanical chuck is provided to carry a workpiece to be processed, the mechanical chuck being a mechanical chuck provided by any of the above embodiments of the invention.
- FIG. 1 is a cross-sectional view of a conventional PVD apparatus.
- FIG. 2A is a partial cross-sectional view of a fixing assembly of a mechanical chuck according to an embodiment of the invention.
- FIG. 2B is a top view of a fixing assembly of a mechanical chuck according to an embodiment of the invention.
- FIG. 3 is a cross-sectional view of a plasma processing apparatus according to an embodiment of the invention.
- FIG. 2A is a partial cross-sectional view of a fixing assembly of a mechanical chuck according to an embodiment of the invention.
- FIG. 2B is a top view of the fixing assembly of the mechanical chuck according to an embodiment of the invention.
- the mechanical chuck includes a base (not shown in the drawings) for carrying a workpiece 25 to be processed, and a fixing assembly 20 .
- the fixing assembly 20 has a multilayer structure, and specifically includes a locking ring 21 , an insulation ring 23 and an spacer ring 22 sequentially stacked from bottom to top, wherein the locking ring 21 is used for pressing an edge region of the workpiece 25 disposed on the base during a process so as to fix it onto the base, as illustrated in FIG.
- the spacer ring 22 may be made of metal, insulation material or the like and an orthogonal projection thereof on an upper surface of the locking ring 21 overlaps with the upper surface of the locking ring 21 ; and the insulation ring 23 is used for electrically insulating the spacer ring 22 from the locking ring 21 , and is made of a material including ceramic or quartz.
- the insulation ring 23 may be an insulation layer provided on the upper surface of the locking ring 21 .
- the insulation ring 23 may be formed by plating an insulation material onto the upper surface of the locking ring 21 .
- the fixing assembly 20 further includes an insulation screw 24 used for fixing the locking ring 21 , the insulation ring 23 and the spacer ring 22 together.
- the insulation ring 23 electrically insulates the spacer ring 22 from the locking ring 21 , the voltage of spacer ring 22 is floating, that is, when RF power supply supplies RF power to the base to form a negative bias voltage on the upper surface of the workpiece 25 , the RF voltage is not applied to the spacer ring 22 , and since the orthogonal projection of the spacer ring 22 on the upper surface of the locking ring 21 overlaps with the upper surface of the locking ring 21 , the entire upper surface (as shown in FIG.
- the capacitor area of the mechanical chuck provided by the embodiment shrinks to the area of the upper surface of the workpiece 25 , so the negative bias voltage formed on the upper surface of the workpiece 25 can be increased without increasing RF power, thereby improving resputter rate.
- an inner circumferential wall of the insulation ring 23 , a portion of the upper surface of the locking ring 21 inside the inner circumferential wall and a portion of a lower surface of the spacer ring 22 inside the inner circumferential wall form a first groove 26 together
- an outer circumferential wall of the insulation ring 23 , a portion of the upper surface of the locking ring outside the outer circumferential wall and a portion of the lower surface of the spacer ring 22 outside the outer circumferential wall form a second groove 27 together.
- the insulation ring 23 has a length smaller than that of the locking ring 21 and is provided at a position close to the middle between the locking ring 21 and the spacer ring 22 .
- the inner circumferential wall of the locking ring 21 and the inner circumferential wall of the spacer ring 22 are substantially aligned in a vertical direction, and the outer circumferential wall of the locking ring 21 and the outer circumferential wall of the spacer ring 22 are substantially aligned in the vertical direction, so that the inner and outer circumferential walls of the insulation ring 23 are inwardly recessed relative to the inner circumferential walls of the locking ring 21 and the spacer ring 22 and the outer circumferential walls of the locking ring 21 and the spacer ring 22 , respectively, to form ring-shaped deep grooves (i.e., the second groove 27 and the first groove 26 ).
- first groove 26 and the second groove 27 plasma can be prevented from being deposited onto the surface of the insulation ring 23 , and thus electrical connection between the spacer ring 22 and the locking ring 21 due to the deposition of metal onto the insulation ring 23 can be avoided, thereby allowing the spacer ring 22 and the locking ring 21 to be electrically insulated from each other throughout the process.
- a ratio of the depth L 1 of the first groove 26 to the width H thereof is larger than 7:1
- a ratio of the depth L 2 of the second groove 27 to the width H thereof is larger than 7:1.
- each of the widths of the first groove 26 and the second groove 27 is smaller than 3 mm, which may be suitable for the case where the mean free path of the plasma is around 3.3 mm.
- the sum of the heights of the insulation ring 23 and the spacer ring 22 in a direction perpendicular to the upper surface of the locking ring 21 should be no larger than 8 mm, so as to avoid that plasma fails to reach the edge region of the upper surface of the workpiece 25 due to the shadow effect of the insulation ring 23 and the spacer ring 22 to adversely affect uniformity of the process.
- FIG. 3 is a cross-sectional view of a plasma processing apparatus provided by an embodiment of the present invention.
- the present invention further provides a plasma processing apparatus, which includes a reaction chamber 30 , and a target material 31 is provided at the top inside the reaction chamber 30 and is electrically connected to a DC power supply (not shown in the drawings).
- a mechanical chuck is provided below the target material 31 inside the reaction chamber 30 , and includes a base 32 and a fixing assembly 20 , wherein the base 32 is used for carrying a workpiece 25 to be processed and is electrically connected to a RF power supply (not shown in the drawings), and the fixing assembly 20 is the fixing assembly provided by the embodiments of the present invention and is used for fixing the workpiece 25 onto the base 32 .
- a negative bias voltage is applied to the target material 31 by the DC power supply to excite a process gas in the reaction chamber to form plasma, and attract energetic particles in the plasma to bombard the target material 31 , so as to allow metal atoms on a surface of the target material 31 to escape and to be deposited on the workpiece 25 .
- RF power is applied to the base 31 by the RF power supply to form a negative bias voltage on an upper surface of the workpiece 25 , which can attract the sputtered metal atoms to be deposited into the through silicon via, thereby filling the through silicon via.
- the negative bias voltage formed on the upper surface of the workpiece to be processed can be increased without increasing RF power, thereby improving resputter rate.
- the mechanical chuck according to embodiments of the invention fixes the workpiece to be processed on the base by means of the fixing assembly, which has a multilayer structure and specifically includes a locking ring, an insulation ring and an spacer ring sequentially stacked from bottom to top, wherein the locking ring is used for pressing an edge region of the workpiece disposed on the base during the process so as to fix the workpiece onto the base; an orthogonal projection of the spacer ring on an upper surface of the locking ring overlaps with the upper surface of the locking ring; and the insulation ring is used for electrically insulating the spacer ring from the locking ring.
- the fixing assembly which has a multilayer structure and specifically includes a locking ring, an insulation ring and an spacer ring sequentially stacked from bottom to top, wherein the locking ring is used for pressing an edge region of the workpiece disposed on the base during the process so as to fix the workpiece onto the base; an orthogonal projection of the spacer ring on an upper surface of the locking ring overlaps with
- the insulation ring electrically insulates the spacer ring from the locking ring, the voltage of spacer ring is floating, that is, when RF power is applied to the base by the RF power supply to form a negative bias voltage on the upper surface of the workpiece, the RF voltage is not applied to the spacer ring, and since the orthogonal projection of the spacer ring on the upper surface of the locking ring overlaps with the upper surface of the locking ring, the entire upper surface of the locking ring does not contribute to the capacitor area due to the shielding of the spacer ring, that is, the capacitor area of the mechanical chuck is only the area of the upper surface of the workpiece, so the negative bias voltage formed on the upper surface of the workpiece can be increased without increasing RF power, thereby improving resputter rate.
- first groove which is formed by the inner circumferential wall of the insulation ring, the portion of the upper surface of the locking ring inside the inner circumferential wall and the portion of a lower surface of the spacer ring inside the inner circumferential wall
- second groove which is formed by the outer circumferential wall of the insulation ring, the portion of the upper surface of the locking ring outside the outer circumferential wall and the portion of the lower surface of the spacer ring outside the outer circumferential wall
- plasma can be prevented from being deposited on the surface of the insulation ring, so it can avoid electrical connection between the spacer ring and the locking ring due to the deposition of metal onto the insulation ring, thereby allowing the spacer ring and the locking ring to be electrically insulated from each other throughout the process.
- the negative bias voltage formed on the upper surface of the workpiece can be increased without increasing RF power, thereby improving resputter rate.
- Embodiments of the invention may suitably comprise, consist or consist essentially of the elements disclosed and may be practiced in the absence of an element not disclosed.
